Hey, I have searched all over and cannot figure out how to do this…
I am working with character models which have Shape Key animations for facial expressions. I need to use these models in the iOS/xcode SceneKit framework, which only accepts 3d data in COLLADA format.
I can get armature and regular keyframe animations to work just fine in Scenekit, but cannot get the ShapeKey based stuff to transfer.
I know that COLLADA can now support Shape Keys, but it seems to hold then not for animation, just for importing into blender use.
So, this leads me to thinking that ‘baking’ the Shape Key-Keyframe-animations into a mesh/vertex animation will do what I am wanting, but I am not sure if/how this is possible.
TLDR- How can I use Shapekey animations outside of Blender…
